How Is Gold Extracted From Gold Ore? Sciencing

Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore.

Gold parting - Wikipedia

Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate.
